[Bug 342359] Re: [jaunty] ubuntu-vm-builder crashed with ioctl in create()

[Jamie Strandboge]

I noticed a bunch of loopback files were not removed after several runs:
$ sudo losetup -a
/dev/loop0: [0802]:1712191 (/tmp/vmbuilderoz9Ae3/disk0.img)
/dev/loop1: [0802]:1712192 (/tmp/vmbuilderZ25Vlg/disk0.img)
/dev/loop2: [0802]:1712199 (/tmp/vmbuilderMYw8D9/disk0.img)
/dev/loop3: [0802]:1712202 (/tmp/vmbuildertNVvQu/disk0.img)
/dev/loop4: [0802]:1712205 (/tmp/vmbuilderdfXyav/disk0.img)
/dev/loop5: [0802]:1712208 (/tmp/vmbuilderPyYKWF/disk0.img)

So then I tried to see why:
$ sudo lsof | grep loop[0-5]
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/jamie/.gvfs
